ChangesWe decided to add in a small motor which turns either to the left or right so because we wanted t incorporate something that would also turn by itself, we added pieces onto it so that it moves the marble in the pinball machine. We also are changing the idea of having a spring as we thought it would be too difficult so, we allow the ball to come in, still using the pulley system but now we have a rubber band which is pulled back with a wooden handle therefore pushing the marble forward when let go! We also took off the canvas pieces because we had extra cardboard which was more reliable and easier to manipulate. BuildingAfter we had looked at the blocks of wood that we had made we put on the cardboard and later we had to cut a small portion off of the side so that we can put in the motor. We also have a piece of wood so that the motor can settle onto it. The motor's control is hot glued onto that piece of wood so that it stays in one spot.
